Lauraceae is among the largest and floristically most important woody plant families in subtropical and tropical zones. However, the Cenozoic fossil records of Lauraceae are mostly from mid-latitude regions. Here we described eight lauraceous species from the Oligocene of Ningming, Guangxi, South China on the basis of leaf compressions with cuticular structure, providing new evidence for high diversity of Lauraceae in the low latitude region of the northern hemisphere during the late Paleogene. The extant genera to which the Ningming Oligocene fossils are possibly closely related include Cinnamomum, Neolitsea, Litsea, Alseodaphne, Laurus, and Beilschmiedia. All of these extant genera except Laurus still exist in Guangxi today, whereas Laurus is currently distributed in the Mediterranean and adjacent regions. A cladistic analysis based on leaf architectural and leaf cuticular characters for Paleogene Lauraceae species in the world indicated a possible relationship between European and East Asian Paleogene species.

O Parque Estadual das Lauráceas é o maior parque estadual no Paraná, sul do Brasil. Localiza-se nos municípios de Adrianópolis, Bocaiúva do Sul e Tunas do Paraná, em uma área montanhosa do Primeiro Planalto Paranaense, conhecida como Serra do Açungui, a qual faz parte da bacia do rio Ribeira. O parque é quase que totalmente coberto pela Floresta Ombrófila Densa e, como seu nome sugere, tem considerável presença de árvores da família Lauraceae. Apesar disso, faltava informação detalhada sobre esse grupo de plantas na área. O objetivo principal desse trabalho é gerar conhecimento sobre suas espécies, reunindo informações que possam auxiliar a gestão dessa unidade de conservação. No primeiro capítulo nós apresentamos o tratamento taxonômico das espécies que ocorrem no parque e em sua zona de amortecimento. Foi elaborada chave de identificação, descrições, dados sobre distribuição geográfica e fenologia, pranchas fotográficas, além de comentários que auxiliam a identificação de cada uma delas. Constatamos a existência de 51 espécies distribuídas em dez gêneros, o que representa a maior riqueza de espécies já registrada por um estudo taxonômico regionalizado para a família no sul do Brasil. No segundo capítulo nós analisamos uma comunidade de Lauraceae dominante em um remanescente muito bem conservado dentro do parque, buscando descrever sua estrutura, e com isso, resgatar a discussão sobre os estágios sucessionais das florestas sul brasileiras através da sua comparação com diversos parâmetros. Para isso, realizamos uma amostragem fitossociológica de dois hectares de floresta. Constatamos que a família é capaz de se organizar em uma comunidade complexa inserida na matriz florestal, com vários estratos, várias idades e várias espécies, com características de estágio clímax. Concluímos também que o parque possui uma associação vegetal tipo Ocotietum, que é uma tendência para os estágios sucessionais mais desenvolvidos da Floresta Ombrófila Densa Montana subtropical. No terceiro capítulo nós revisamos a distribuição geográfica das espécies que foram identificadas no parque, buscando compreender essa comunidade no contexto brasileiro, em especial no Bioma Mata Atlântica. Para isso, realizamos análises de similaridade florística com outras 46 comunidades no bioma e também análises de espécies indicadoras. Constatamos a formação de sete grupos florísticos. A comunidade do parque ficou agrupada com outras quinze, todas situadas na região montanhosa ao longo da costa Atlântica, entre os estados do Rio de Janeiro e Santa Catarina. Esse grupo florístico de Lauraceae é aqui denominado como “Serra do Mar”, para o qual foram selecionadas 17 espécies indicadoras.

The Lauráceas State Park is the largest state park in Paraná, southern Brazil. It is located in the municipalities of Adrianópolis, Bocaiúva do Sul, and Tunas do Paraná, on a mountainous area of Paraná’s First Plateau (Primeiro Planalto Paranaense) known as Açungui mountain range, which is part of the Ribeira river basin. The park is nearly entirely covered by Atlantic Rainforest and, as its name suggests, it has a large presence of trees of the Lauraceae family. Nevertheless, detailed information about this group of plants in the area was lacking. The main goal of the present paper is to generate knowledge about its species, gathering information that may be helpful on the management of this conservation unit. In the first chapter we present the taxonomic treatment of the species that occur in the park and in its buffer zone. Identification keys, descriptions, data on geographic distribution and phenology, and photographic plates are provided, as well as comments that help to identify each species. We found 51 species distributed in ten genera, which represent the greatest species richness recorded by a regionalized taxonomic study for the family in southern Brazil. In the second chapter we analyzed a dominant community of Lauraceae in a very well preserved remnant within the park, aiming to describe its structure, and with this, we bring up the discussion about the succession stages of the Brazilian forests through the comparison of several parameters. For this, we performed a phytosociological sampling of two hectares of forest. We verified that the family is able to organize itself in a complex community inserted in the forest matrix, with several strata, several ages and several species, with characteristics of climax stage. We conclude also that the park has an Ocotietum type of vegetation, which is a tendency for the most developed successional stages of the subtropical Montane Atlantic Rainforest. In the third chapter we review the geographic distribution of the species that were identified in the park, searching to understand this community in the Brazilian context, especially in the Atlantic Forest Biome. For this, we performed analyses of floristic similarity including other 46 communities from the same biome, and also analyses of indicator species. Seven floristic groups were recovered. The park community was grouped with fifteen others, all located in the mountainous region along the Atlantic Ocean, between the states of Rio de Janeiro and Santa Catarina. This particular floristic group of Lauraceae is here named "Serra do Mar", for which 17 indicator species were selected.

Lauraceae está entre as três principais famílias do componente arbóreo das florestas no Paraná, sendo elemento frequente nos estudos fitossociológicos e biogeográficos. Apesar disso, a família continua insuficientemente conhecida no estado. Nossos objetivos foram: reconhecer as espécies de Lauraceae no Paraná, relacionando-as com as unidades fitogeográficas; mapear as regiões com maior riqueza de espécies e concentração de endemismos; identificar áreas de complementaridade e compará-las com as áreas prioritárias para conservação. Para isso, nós utilizamos registros de coleções de 23 herbários nacionais, totalizando 3.332 espécimes analisados, plotando suas coordenadas no mapa fitogeográfico do estado. Constatamos que no Paraná ocorrem 76 espécies, das quais onze são citadas pela primeira vez no estado. A Floresta Ombrófila Densa abrange o maior número de espécies (59 spp.), seguida pela Floresta Ombrófila Mista (31 spp.), Floresta Estacional Semidecidual (23 spp.), Savana (9 spp.) e Estepe (2 spp.). As regiões da Serra do Mar e Vale do Ribeira apresentam a maior riqueza e endemismo. O Parque Estadual das Lauráceas é uma unidade de conservação estratégica, pois abriga dois terços das espécies paranaenses, com sete endêmicas.

Lauraceae are among the three main families of the arboreal component of the forests in Paraná, being a frequent element in phytosociological and biogeographic studies. In spite of this, the family remains insufficiently known in the state. Our aims were: to recognize the species of Lauraceae in Paraná, relating them to the phytogeographic units; map the regions with the greatest species richness and concentration of endemisms; identify complementarity areas and compare them with the priority areas for conservation. We used collection records from 23 national herbaria, totaling 3,332 specimens analyzed, plotting their geographic coordinates onto the phytogeographic map of the state. We found that there are 76 species in Paraná, of which eleven are cited for the first time in the state. The Atlantic Rainforest contains the largest number of species (59 spp.), followed by the Araucaria Rainforest (31 spp.), Semideciduous Forest (23 spp.), Savanna (9 spp.), and Grasslands (2 spp.). The Serra do Mar and Ribeira Valley regions have the highest concentration of species, as well as the highest index of endemism. The Lauráceas State Park is a strategic conservation unit, because it houses two thirds of the species of Paraná, including seven endemic.

Tropical and subtropical amphi-Pacific disjunction is among the most fascinating distribution patterns, but received little attention. Here we use the fossil-rich Cinnamomum group, a primarily tropical and sub-tropical Asian lineage with some species distributed in Neotropics, Australasia and Africa to shed light upon this disjunction pattern. Phylogenetic and biogeographic analyses were carried out using sequences of three nuclear loci from 94 Cinnamomum group and 13 outgroup samples. Results show that although there are three clades within a monophyletic Cinnamomum group, Cinnamomum and previously recognized subdivisions within this genus were all rejected as natural groups. The Cinnamomum group appears to have originated in the widespread boreotropical paleoflora of Laurasia during the early Eocene (ca. 55 Ma). The formation and breakup of the boreotropics seems to have then played a key role in the formation of intercontinental disjunctions within the Cinnamomum group. The first cooling interval (50–48 Ma) in the late early Eocene resulted in a floristic discontinuity between Eurasia and North America causing the tropical and subtropical amphi-Pacific disjunction. The second cooling interval in the mid-Eocene (42–38 Ma) resulted in the fragmentation of the boreotropics within Eurasia, leading to an African–Asian disjunction. Multiple dispersal events from North into South America occurred from the early Eocene to late Miocene and a single migration event from Asia into Australia appears to have occurred in the early Miocene.

A phylogenetic analysis based on nuclear ITS and plastid trnK intron sequences confirms that Dahlgrenodendron, Sinopora, Triadodaphne, and Yasunia are members of the Cryptocarya group, as expected from morphology.  Dahlgrenodendron from South Africa is sister to Aspidostemon from Madagascar. Triadodaphne inaequitepala is nested within Endiandra (both from Australasia), and Yasunia from South America is nested among South American Beilschmiedia species. Sinopora is a member of the Beilschmiedia clade, but its precise position is still uncertain.  Among large genera of the group, Cryptocarya is clearly monophyletic, and Endiandra appears to be as well, if T. inaequitepala is included. Beilschmiedia is paraphyletic with respect to (at least) Potameia and Yasunia. Most well-supported clades within genera are geographically homogeneous, except a clade including the Chilean Cryptocarya alba and two New Caledonian species. Both Beilschmiedia and Cryptocarya have reached the Americas more than once.  Four-locular anthers are plesiomorphic in the Cryptocarya group; two-locular anthers have arisen by fusion of the two pollen sacs of a theca. In the plesiomorphic fruit type, the ovary is completely enclosed in receptacular tissue; a superior fruit, seated free on its pedicel, is a synapomorphy of the Beilschmiedia clade.
